Detailed Implementation

[0035] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0036] like Figures 1 to 4 As shown, an embodiment of this utility model provides an elevator operation guidance device, comprising:

[0037] The main frame 1 and the guide column 2 are provided. The main frame 1 is provided with a first slide groove 301 and a second slide groove 302. The guide column 2 is an external part.

[0038] Connecting frame 303 and connecting frame 304 are slidably connected to the inner surfaces of sliding groove 301 and sliding groove 302, respectively.

[0039] Adjustment mechanism 3, which is set on the outer surface of the main frame 1, is used to adjust the distance between the wheel and the column so that the wheel and the column can fit together tightly;

[0040] The buffer mechanism 4 is disposed on the surface of the adjustment mechanism 3, which reduces surface wear when the wheel is working and makes the wheel fit more closely to the column.

[0041] like Figure 2As shown, the adjustment mechanism 3 includes a motor 310, which is threaded onto the main frame 1 via a slotted bolt 309. A bidirectional threaded rod 311 is fixedly connected to the working end of the motor 310. The bidirectional threaded rod 311 is threaded in the forward direction to a first connecting frame 303, and threaded in the reverse direction to a second connecting frame 304. When the motor 310 operates, it drives the bidirectional threaded rod 311 to rotate, causing the first connecting frame 303 and the second connecting frame 304 to move in opposite directions along the bidirectional threaded rod 311.

[0042] like Figure 2 As shown, a bearing 312 is embedded in the surface of the main frame 1, and one end of the bidirectional threaded rod 311 is embedded inside the bearing 312. When the bidirectional threaded rod 311 rotates, the bearing 312 makes the bidirectional threaded rod 311 rotate more smoothly.

[0043] like Figure 2 As shown, a first fixing rod 305 and a second fixing rod 306 are fixedly connected to one side surface of the first connecting frame 303 and the second connecting frame 304, respectively. A first guide wheel 307 and a second guide wheel 308 are rotatably connected to the outer surfaces of the first fixing rod 305 and the second fixing rod 306, respectively. During operation, the first guide wheel 307 and the second guide wheel 308 can rotate on the first fixing rod 305 and the second fixing rod 306 connected to the first connecting frame 303 and the second connecting frame 304.

[0044] like Figure 2 As shown, a limiting block 313 is welded to the middle surface of the main frame 1, and the bidirectional threaded rod 311 is rotatably connected inside the limiting block 313. The limiting block 313 is the dividing point between the first connecting frame 303 and the second connecting frame 304, and can limit the first connecting frame 303 and the second connecting frame 304 from moving too much inward.

[0045] In this embodiment of the utility model, the operation of the motor 310 first drives the bidirectional threaded rod 311 to rotate. The bearing 312 makes the bidirectional threaded rod 311 rotate more smoothly. The bidirectional threaded rod 311 drives the first connecting frame 303 and the second connecting frame 304 to move towards the guide post 2 in the first slide groove 301 and the second slide groove 302 respectively, so that the first guide wheel 307 and the second guide wheel 308 can be closely attached to the guide post 2.

[0046] like Figure 2 , Figure 3 and Figure 4As shown, the buffer mechanism 4 includes a first spring 411 and a second spring 412. The outer surfaces of the protrusions of the first connecting frame 303 and the second connecting frame 304 are respectively fixedly connected to a first rotating column 401 and a second rotating column 402. The outer surfaces of the first rotating column 401 and the second rotating column 402 are respectively welded to a first long plate 403 and a second long plate 404. A third rotating column 405 and a fourth rotating column 406 are respectively welded to one end surface of the first long plate 403 and the second long plate 404. The two end surfaces of the third rotating column 405 and the fourth rotating column 406 are respectively rotatably connected to a first connecting shell 407 and a second connecting shell 408. When the distance between the first connecting frame 303 and the second connecting frame 304 changes, one end of the first long plate 403 and the second long plate 404 will rotate due to the rotation of the first rotating column 401 and the second rotating column 402 on the first connecting frame 303 and the second connecting frame 304, and the other end of the first long plate 403 and the second long plate 404 will rotate due to the rotation of the third rotating column 405 and the fourth rotating column 406 on the first connecting shell 407 and the second connecting shell 408.

[0047] like Figure 3 As shown, a first sliding block 409 and a second sliding block 410 are slidably connected to the inner surfaces of the first connecting shell 407 and the second connecting shell 408, respectively. A nut 415 is embedded in the outer surface of the first sliding block 409. A first spring 411 and a second spring 412 are welded to one side surface of the first sliding block 409 and the second sliding block 410, respectively. The first sliding block 409 and the second sliding block 410 are slidably connected inside the first connecting shell 407 and the second connecting shell 408, and the first spring 411 and the second spring 412 provide a buffering force for the first connecting shell 407 and the second connecting shell 408.

[0048] like Figure 3 As shown, a threaded rod 413 is connected through the inner surfaces of the first sliding block 409 and the second sliding block 410. A third guide wheel 414 is rotatably connected to the outer surface of the threaded rod 413. The threaded rod 413 and a nut 415 are threadedly connected. The nut 415 connects to the threaded rod 413, so that the threaded rod 413 can be firmly fixed to the first sliding block 409 and the second sliding block 410. The third guide wheel 414 is rotatably connected to the threaded rod 413 and can rotate.

[0049] In this embodiment of the utility model, when the distance between the first connecting frame 303 and the second connecting frame 304 changes, one end of the first long plate 403 and the second long plate 404 will rotate due to the rotation of the first rotating column 401 and the second rotating column 402 in the first connecting frame 303 and the second connecting frame 304. The other end of the first long plate 403 and the second long plate 404 will rotate due to the rotation of the third rotating column 405 and the fourth rotating column 406 in the first connecting shell 407 and the second connecting shell 408. This ensures that the third guide wheel 414 remains in a straight line. When the third guide wheel 414 slides on the guide column 2, the first spring 411 and the second spring 412 respectively abut against the first sliding block 409 and the second sliding block 410, so that the third guide wheel 414 is always in close contact with the guide column 2. When the guide column 2 rotates, the first sliding block 409 and the second sliding block 410 can play a buffering role.

[0050] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
